WlRE=-STlTCl-IING MACHINE.

EPECIPICATION forming part of Letters Patent No. 391,252, dated October 16, 1888.

Application tiled May 2-1, 1887. Serial No. 239.237.

(No model.) Patented in England April 5, 1887, No. 5,063, and in Germany April 5, 1887, No. 42,7 19.

scription of the invention.

My invention has for its object to adapt wire-stitching machines for the manufacture of round or polygonal card-board boxes, and more especially for securing the bottoms of r 5 such boxes to the sides by means of steel wire.

In the following description reference will be made to the annexed drawings, in which- Figure 1 is a side elevation of a wire-stitching machine embodying myinvention, while Figs. 2 to 5 represent a suitable clinching apparatus on a large scale, Fig. 2 being a front elevation. Fig. 2 is an elevation of the clinching device with the cover-plate removed,showing the clinching-leversin the act of engaging a staple, the view showing, also, a box, partly in section, in position on the work-supporting disk, which is also partly sectioned; Fig. 3, a partly side elevation and partly vertical section, and Fig. 4 a plan of the same, the plate Fig. 5 is a section along line \V \V of Fig. 2. Figs. 6, 7, and 8 represent sections of boxes which may be made by my machine. Figs. 9 and 10 are diagrammatic views of the box-corner and clinching levers,

showing the latter at the commencement and finish of the clinching operation, respectively.

The machine may be similar to that de scribed in my United States Patent,1 lo.378,324, dated February 21, 1888, and in the specifica- 0 tion of the English Patent No. 16,137 of 1884,

with the exception of the saddle and clinching apparatus, which are constituted as follows:

Instead of the vertically-movable saddle A,

(shown in Figs. 12 and 13 of the English Pat- 5 ent,specification No. 16,137 of 1884, and in my aforesaid United States Patent,) 1 employ a curved beam, T, carrying at the top asupporting-disk, P, and rigidly connected at the bottom with an upright arm or guide-plate, t.

This arm 1% is guided vertically by a sleeve, to,

as shown in Fig. 1, or by other convenient means, and pressed upward at the required moment by the motion of the wedge-shaped extremity of the horizontal rod 12, operated by the lever V, Fig. 1; As in my previous machine, the extremity of the rode is situated between a pair of friction-rollers, t t",the bearing of the lower roller being fixed during the operation of the machine, but having means for adjusting them as circumstances require, while those of the upper roller are movable with the arm '6'. In the present case the roller t has its bearings in a recess of the arm t, while the lower roller is held in a shackle, t, pro vided with a screw-spindle, t, which allows the roller to be placed higher or lower by turning the hand-wheel i The beam T is shaped in cross-section, as shown by Fig. 5, and carries at the top the clinching mechanism, which is movable vcrtically between a pair of guide-plates, 99, secured to its side by v means of screws .2 z. The platef, carrying at the top the clinching-plates cc, Fig. 2, is connected at the bottom with an oscillatinglever, h, pivoted to the side of the beam T by means of the screw This lever is connected by a pin or stud with the upper end of a rod, 8, joined at the lower end to an anglelevcr, 0", having its fulcrum at the back of the beam T, as shown in Figs. 3 and 4. The angle'lever r is in contact with the extremity of an adj ustable screw stud,p, secured to the operatinglever O.

As shown in Fig. 2, the upper part of the beam T isinclined and provided with aslottcd disk, P, partly or wholly curved at its circumference, and made exchangeable, so as to suit the shapes and sizes of the boxes to be made.

The plate P has a slot, as before mentioned, through which the upper end of the beam T and the plates g g emerge, so that the face of the beam T and the plates 9 g are flush with the upper surface of the plate P, in order that the corner of the box being stitched will be at a point over the clinehinglevers midway between the upper ends of the latter. The plate P is secured to the beam T by means of ashort angle-iron, 12, secured to the bottom of the plate and to the side of the beam by means of 100 oted to the sliding platefby means of pins 2 2, adapted to have their upper eudsseparated when the barf is lowered, by coming in contact with the oblique cam-faces e e, which may be formed integral with one of the plates 9 g. The construction and operation of this mechanism, however, is exactly analogous to that which forms an important part of the subject-matter of my earlier patent aforesaid, and will not, therefore, require a detailed description here.

The operation of stitching is as follows: The

side or cylindrical part of the box 1" or receptacle to be formed is placed endwise over the beam T, as shown in Figs. 2 and 2, and the bottom of the box on the plate Pin such a manner that the edge of the cylinder or side coincides with the edge of the bottom, or that one part slightly overlaps the other. Thereupon the staple is formed, in the usual manner, in the upper part of the machine and driven into the side and bottom of the box through the slot 1' between the plates 9 g by the beam T being pushed upward against the stapleforming head R, which motion is caused by the wedge-shaped extremity of the rod '0 being drawn between the friction-rollers t t. The ends of the staple projecting into the interior of the box, as shown in Figs. 2 and 9, are now caught on the outside by the inner oblique faces of the levers ec, which are moved upward by the barf, and during the further ascension of said bar the upper ends of the levcrs e are forced toward each other by coming in contact with the converging faces 1*",

which action will bend the ends of the staple to the position shown in Fig. 9. Now, as the upward motion of the boX is continued still farther, the upper ends of the levers will come together and strike upon the stop 1*", which action will place the ends of the staple on the outside of the levers, whereby further upward motion of the latter will cause the staple ends to be pressed firmly against the side and bottom of the box. It is of course understood that the barf is operated, through the medium of the lever h and rod 8 and angle-lever r, by

. the operating-lever O pushing the screw-stud into contact with the anglelever r. After one staple has thus been applied the beam T is again lowered, the box shifted on the plate P the distance of two staples, and the operation is repeated.

What I claimis- I 1. The combination, with a staple-forming head, R, the beam T, suitable means for imparting a vertical reciprocating motion to said beam, and clinching mechanism carried by said beam,of a work-supporting plate secured to the end of said beam and having a peripheral slot for the reception of the end of the beam and said clinching mechanism, substantially as set forth.

' 2. The combination, with a staple forming head,R, the beam T, suitable means for imparting a vertical reciprocating motion to said whereby the said end will be flush with the,

surface of said plate.

3. The combination, with a staple-forming head, R, the obliquely-arranged beam T, suitable means for imparting a vertical reciprocating motion to said beam and the clinching mechanism, of a work-supporting disk or plate secured transversely to the end of said beam and having a slot from its periphery inward for the reception of said beam and clinching mechanism, the rods, the lever h, pivoted to said rod and clinching mechanism and also to beam T, the operating-lever 0, having a, stud or projection thereon, and a pivoted angle-lever attached to the rod 8, as set forth.

4. The combination, with the staple-forming head R, having an angular notch therein, of a vertically-movable beam, a plate secured to the end of said beam at an angle equal to the angle of said notch, and having a slot in.

which the end of said beam fits, and clinching mechanism having upper faces at an angle corresponding to that formed by the beam and plate and projecting flush with the end ofsaid beam, substantially as set forth.

In testimony whereofI have signed this specification in the presence of two subscribing witnesses.
